REVERSE OSMOSIS UNDER SINK WATER PURIFICATION ON THE CHEAP.
Just completed the yearly filter change in my R.o.m system
this week.
Set the system up as not to discharge any ‘non pure’ water to the drain and have instead piped it to a 5 litre container which you can use for cooking water or kettle water when full.
During the course of a couple of years I have done a bit of testing and found that to make one litre of filtered water the unit would dispel a fair bit down the drain- pure waste- this discharged water has come from a local authority source deemed safe to drink then it has passed through five filters in my r.o.m set up(the end product passes through a sixth filter)so it makes sense to save it for cooking, drinking water for pets, washer bottle in the car etc.
In order to do this just simply turn the water supply off when
the unit is not in use and instead of putting the discharge pipe to the drain -
push it into a empty container – the discharge continues to drip for about two
hours after turning off the unit and will take about a week to fill up a 5
litre bottle if like me you draw off about 4 litres of pure filtered water
every day.
The system itself cost around 125 euro(price includes a filter set for 12 months use) a few years ago from www.thewaterfiltermen.ie and was simple to install by yourself. You need a fair bit of space to mount the unit (set mine up in the shed)and you will need at least 1.5 bar of water pressure from a incoming mains water pipe-no electric is needed if you have the minimum mains water pressure.
The filters need changing once every year and cost around 50Euro from the waterfilter men.ie.
Saved me money, time and the environment over the years from not having to buy bottled water.
